NVIDIA's Spectrum-X silicon photonics Ethernet technology is now in full production. The next-generation Spectrum-X switch uses co-packaged optics (CPO) and supports the Vera Rubin platform for data-center horizontal scaling and cross-region AI factory deployments. NVIDIA says Spectrum-X can deliver 5x network energy efficiency versus networks using traditional transceivers, 5x improvement in AI uptime, and 1.3x faster deployment.
